Abstract

A wireless communication network serves a wireless User Equipment (UE) over a working network slice and a protect network slice. In the wireless communication network, the UE transfers UE capability data to a network control-plane that indicates the working network slice and the protect network slice. The network control-plane generates UE context for the working network slice and the protect network slice. The network control-plane signals the UE context to the UE and to a network user-plane. The UE and network user plane exchange user data over the working network slice based on the UE context. The UE determines when the performance of the working network slice triggers a slice switch based on the UE context. In response to the slice switch, the UE stops using the working network slice. The UE and network user-plane exchange user data over the protect network slice based on the UE context.
